Title: Improvements in or relating to hoists
IPC: B66D1/26
Filed: 1939-05-06
Abstract: 528,423. Winches. INGERSOLL-RAND CO. May 6, 1939, No. 13601. Convention date, May 12, 1938. [Class 78 (v)] A power-driven hoist of the multi-drum type in which any drum may be selectively driven from a common driving shaft has means whereby drums with their casings may be added or removed from the assembly. Fig. 1 shows two drums 24, 25 mounted respectively in barrel-like casings, 26, 27. The casing 26 has an end-plate 32 bolted thereto together with a motor-supporting distance piece 34, through which passes the shaft 35 of a motor 23. Between the casings 26 and 27 is a transverse plate 30, and the outer end of casing 26 is closed by a plate 31. The drum shaft 43 is driven by gear wheels 37,38,41, 42 from the motor shaft 35, and is journalled by anti-friction bearings 44, 45 in the end plates 32, 31. A series of sun-wheels 49 are mounted on the shaft 43, one for each drum, and these engage planet pinions 59 of an epicyclic gear, the internally toothed outer wheel 60 of which is bolted to disc webs 66 journalled respectively on a boss on the plate 30 and on a sleeve 51 extending from the pinion cage 54 and having its end running in an anti-friction bearing 62 carried by the plate 32. The drums 24, 25 are rigidly connected to these sleeves 51 by keys 53. The sleeves 51 do not contact with the shaft 43, thus both avoiding transmission of a bending load from the drums to the shaft 43 and providing a channel 61 for oil to reach the bearings 62, 44. An oil duct 73 runs through the plate 30 and communicates with the chamber formed by the discs 66 and containing the epicyclic gear, packing members 70 sealing joints past which it is not desirable that oil should percolate. The outside of each wheel 60 is braked by a band 77 tightened by a handle 80 pivoted to one end of the band and coupled to the other end. Springs normally pull the ends of the band away from the braking position, and adjustable stops bear against projections on the band to prevent rotation of the band when engaged. A foot-operated brake shoe bears against a rim 91 extending from the cable drum, a spring being preferably provided to put this shoe in constant slight contact to prevent free spinning of the drum. When drums are added or removed the shaft 43 is replaced by one of the required length.

Title: Combined television and sound receiver system
IPC: H04N7/084
Filed: 1945-06-01
Abstract: 592,741. Television receivers; pulse multiplex signalling. STANDARD TELEPHONES & CABLES, Ltd. June 1, 1945, No. 13816. Convention date, June 12, 1944. [Classes 40 (iii) and 40 (v)] A receiver for' combined television and sound signals in which the sound signals comprise time modulated pulses occurring during the horizontal blanking intervals employs the sawtooth voltage source of the image reproducer for the demodulating wave of the sound channel pulse demodulator. The combined signals are amplified and detected in channel 6, Fig. 2, which may include a R.F. amplifier, a mixer, I.F. amplifier and seconddetector. The output of this channel curve a, Fig. 1, comprising vision signals 2, blanking signals 3, synchronising pulses 4 and sound pulses 5 is passed through a threshold clipper 7, Fig. 2, which produces the signal b, Fig. 2. This signal which is fed to a saw-tooth generator 9, adapted to be triggered by the synchronizing pulses 4 but which is not affected by'the sound pulses 5, is also fed to the first grid of valve 12 via the condenser 13 which has a capacity such that when a first pulse reaches the grid, grid current flows and 13 is charged thereby applying a negative potential to the grid which is sufficiently high so that 12 accepts only the tips of the pulses. The amplitude of these pulses should be at least large enough to drive the valve to plate current cut-off. The output of generator 9, curve c, Fig. 1, which provides scanning signals for the image reproducer 11, Fig. 2, is fed to the second grid of valve 12 so that when each of the pulses 4 appears on the first grid the potential of wave 10 is at its lowest point 15. At a time between points 15 and 16, determined by the time modulation of the individual pulses, one of the pulses 5 appears and the resultant output of the valve 12, curve d, Fig. 1, in which the amplitude of the sound pulses 5 defining the sound signal envelope 18 is proportional to the time interval between pulses 4 and 5, is fed via a low pass filter 17, Fig. 2, to the audio reproducer 19.
